Epic Games demonstrate real-time ray tracing in Unreal Engine 4 with ILMxLAB and NVIDIA

The line between gaming and cinema animation blurs even further as ILMxLAB, NVIDIA, Epic Games and Unreal Engine 4 collaborate to present familiar characters from The Force Awakens and The Last Jedi.

During today’s “State of Unreal” opening session at the Game Developers Conference (GDC), the three companies presented an experimental cinematic demo using Star Wars characters from The Force Awakens and The Last Jedi built with Unreal Engine 4. The demonstration is powered by NVIDIA’s RTX technology for Volta GPUs, available via Microsoft’s DirectX Ray Tracing API (DXR). An iPad running ARKit is used as a virtual camera to draw focus to fine details in up-close views.

Epic built the computer-generated (CG) scene using assets from Lucasfilm’s Star Wars: The Last Jedi featuring Captain Phasma, clad in her distinctive armor of salvaged chromium, and two stormtroopers who run into her on an elevator on the First Order ship. In the tech demo, lighting is moved around the scene interactively, as the ray-traced effects including shadows and photorealistic reflections render in real time. The stunning image quality of highly reflective surfaces and soft shadows has never before been achieved at such a high level of image fidelity in Unreal Engine.

I can’t hope to do the technical aspects of this process justice, so head on over to UnrealEngine.com and read further.
